"Doug had a crazy pre-baby bucket list," she shares. "He wanted to swim with sharks, sky dive, go on a 'real' ghost hunt -- crazy things that I'd never do. But I wanted to conquer his dreams with him."

"I wanted to grow closer to him," the reality star adds. "Most importantly, I wanted him to feel READY to be a dad before we got pregnant."

After the couple did everything on the bucket list, she says. "Doug asked me to start trying for a baby. Two months later we found out we were pregnant!"

The TV personality's husband also celebrated the news via Instagram on Tuesday, writing, "#BabyHehner says hello! @jamienotis & I thank all of you for the love and support, and couldn't be happier to share the news the we are pregnant!"
